Fraile, Jose M.,Garcia, Jose I.,Lazaro, Beatriz,Mayoral, Jose A.
, p. 1807 - 1808 (1998)
Several titanium derivatives supported on silica have been investigated as catalysts in the sulfide→sulfoxide oxidation; the supported titanium/tartaric acid catalyst is highly suited to reactions carried out with H2O2, leading to high yields and high sulfoxide/sulfone selectivities, while small asymmetric inductions (up to 13%) are observed.
A Simple Metal Free Oxidation of Sulfide Compounds
Wagh, Ravindra B.,Nagarkar, Jayashree M.
, p. 181 - 187 (2017)
Abstract: This work reports simple, efficient, selective protocol for the oxidation of sulfide compounds. Various sulfides were selectively and completely converted into their corresponding sulfoxides and sulfones using H2O2as an oxidant in presence of catalytic amount of caprylic acid. The reaction proceeds at room temperature to give sulfoxide and by increasing the reaction temperature to 50 °C, this system provides selective formation of sulfone with high conversion and excellent yields. Green, convenient, easy work-up, chemoselectivity, broad substrate scope and regeneration of catalyst are the important highlights of this protocol. Graphical Abstract: [Figure not available: see fulltext.] Using H2O2as an oxidant in presence of catalytic amount of caprylic acid various sulfides were selectively and completely converted into their corresponding sulfoxides and sulfones.

The oxidation of arenes and sulfides by potassium permanganate was accomplished in good yields under solvent free and heterogeneous conditions when manganese(II) sulfate is used as a solid support. After extraction of the organic products, the inorganic products can be reoxidized to permanganate. This result is important because it provides an approach to oxidation reactions that is, in theory, infinitely sustainable. Springer-Verlag 2007.

A highly efficient, green, rapid, and chemoselective oxidation of sulfides using hydrogen peroxide and boric acid as the catalyst under solvent-free conditions
Rostami, Amin,Akradi, Jamal
, p. 3501 - 3503 (2010)
We report boric acid as a highly efficient and eco-friendly catalyst for the selective oxidation of sulfides to sulfoxides or sulfones, in excellent yields under solvent-free conditions, using 30% hydrogen peroxide as an oxidant. Various sulfides possessing functional groups such as alcohol, ester, and aldehyde are successfully and selectively oxidized without affecting sensitive functionalities.

Selective oxidation of sulfides to sulfones was developed using N,N′-dibenzyl-N,N,N′,N′-tetramethylethylene diammonium permanganate. A variety of aromatic and aliphatic sulfides were oxidized to the corresponding sulfones immediately in excellent yields at r.t. Copyright Taylor & Francis Group, LLC.

Mn-porphyrin complex was anchored coordinatively to silica-coated surface of magnetic nanoparticles (SMNP). Afterward, a heterogeneous nanocatalyst (Fe3O4@SiO2-MnTCPP) has been characterized by Fourier transform infrared (FT-IR), ultraviolet-visible (UV-vis) spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), thermogravimetric analysis (TGA), and transmission electron microscope (TEM). A thermal stability up to around 350°C was verified for prepared nanocatalyst based on thermogravimetric analysis. Finally, the catalytic performance of magnetically recoverable Mn-catalyst was exploited in the green oxidation of different sulfides with urea hydrogen peroxide (UHP) in the presence of imidazole as co-catalyst in ethanol under heterogeneous conditions. The eco-friendly property of ethanol strongly induced us to employ it as the reaction solvent in this oxidation system. Complete conversion (≥99) of sulfides to the corresponding sulfoxide or sulfones was obtained for ethyl phenyl sulfide, phenyl vinyl sulfide, diallyl sulfide, thiocyanatoethane, 2-ethyl mercaptoethanol and tetrahydrothiophene. Moreover, the recovered catalysts keep constant conversion yield up to at least three cycles.

A practical and mild method for the switchable synthesis of sulfoxides or sulfonesviaselective oxidation of sulfides using cheapN-fluorobenzenesulfonimide (NFSI) as the oxidant has been developed. These highly chemoselective transformations were simply achieved by varying the NFSI loading with H2O as the green solvent and oxygen source without any additives. The good functional group tolerance makes the strategy valuable.

Two-dimensional (2D) zinc oxides have attracted more and more research interests due to their unique properties. Yet, it remains a great challenge to limit the thickness to the sub-1 nm scale and further combine with other components to obtain 2D hybrid zinc oxide (ZnO)-based sub-1 nm materials. Herein, a versatile strategy was successfully developed to realize the controllable preparation of ZnO-polyoxometalate (POM)-based 2D hybrid sub-1 nm nanosheet (HSNS) superstructures by incorporating three kinds of molybdenum-based POM clusters into the zinc oxide system. Molecular dynamics simulation results demonstrated that POM clusters interact with ZnO/Zn(OH)2molecules and coassembled into stable 2D HSNSs. Significantly, theses materials as robust catalysts showed excellent catalytic activity, selectivity, and stability in the oxidation of thioethers at room temperature, which partly can be attributed to the special 2D sub-1 nm nanostructures with large specific areas leading to the full exposure of active sites. Meanwhile, the synergetic effect of multiple components also played an important role during the catalytic process. Thus, this work would pave the way for the precise synthesis of multicomponent 2D hybrid sub-1 nm materials for widespread applications.
